  1. Rock Cycle

  2. Diagram of the Interior of the Earth Crust0 to 40 km0°C Upper Mantle40 to 670 km1,000°C Lower Mantle670 to 2,890 km2,000°C Outer Core2,890 to 5,150 km3,700°C Inner Core5,150 to 6,370 km4,300°C Prepared by theMichigan Department of Environmental QualityOffice of Geological Survey

  3. Minerals • Minerals – Naturally formed solid that has a repeating three-dimensional shape • Minerals are • Nonliving material • Have crystals • Formed in nature • solid

  4. Identifying Minerals Luster Color Streak Cleavage and Fracture Density Hardness

  5. Streak is simply the color of a mineral powder.

  6. Moh’s Hardness Scale What rock will scratch Calcite but not scratch Orthoclase?

  7. Hardness of some other items:

  8. Mineral Properties Video Clip

  9. Rocks • Minerals combine to form rocks • There are three types of rocks • Igneous • Sedimentary • Metamorphic

  11. Igneous Rock Igneous forms when hot, liquid rock, or magma, cools and hardens Igneous rock formed on the surface is called extrusive Rock formed under surface is intrusive

  12. Extrusive Intrusive

  13. Sedimentary Rocks Sedimentary rocks are formed from compaction and sedimentation Sedimentary contain layers called strata

  14. Metamorphic Rock Metamorphic rock is formed by heat and pressure

  15. + Heat and Pressure =
